The justification for using games in the classroom has been well demonstrated as benefiting students in a variety of ways. These benefits range from cognitive aspects of language learning to more co-operative group dynamics. The benefits are as follows:

Affective:

- games lower the affective filter
- they encourage creative and spontaneous use of language
- they also promote communicative competence
- games are both motivating and fun

Cognitive:

- games reinforce learning
- they both review and extend learning
- games focus on grammar in a communicative manner

Class Dynamics:

- games are extremely student centered
- the teacher acts only as facilitator
- games build class cohesion
- they can foster whole class participation
- games promote healthy competition

Adaptability:

- games can be easily adjusted for age, level, and interests
- they utilize all four skills
- games require minimum preparation after the initial development stage

You can successfully use games in many ways, such as for a quick review, after material has been covered or as a cool-down activity at the end of a lesson to practice what has been covered (as well as to inject an element of fun). You could also use a game to practice specific new language in groups or pairs for a limited time, as a short introduction to new vocabulary or a concept, as a prompt for writing work, even as a link into a new part of the lesson. Games may even be used merely to change the pace of a lesson.
